feat: add twitter X icon to list of approved Bootstrap brandIconNames

[kalebjdavenport]

Description

This PR adds the new Twitter "X" icon which is the updated branding.

Edit (@brian-smith-tcril):

• Rebased on latest
• Updated bootstrap-icons package to 1.11.3 in the icons dir package.json
• Updated copy-brand-icons to look in ./node_modules (the icons directory node modules) instead of ../
• Ran build in icons dir (it seems 1.11.3 made some minor changes to the icons. this is why this PR now has 198 files changed)

https://deploy-preview-2686--paragon-openedx.netlify.app/foundations/brand-icons/

bootstrap-icons changes from 1.10.5 to 1.11.3

Before (1.10.5)

After (1.11.3)
